Multidisciplinary Specialty Care Imperative for Neurofibromatosis Management

Penn State Health Milton S. Hershey Medical Center specialists are working together to form a center for the comprehensive, multidisciplinary management of patients with neurofibromatosis (NF). Leading the team are Dawit Aregawi, MD, assistant professor, neuro-oncology, Kimberly S. Harbaugh, MD, associate professor of neurosurgery, chief, division of peripheral nerve surgery, and Elias Rizk, MD, assistant professor of neurosurgery. The Hershey Medical Center team is focused on adult NF management for better function preservation, earlier detection of cases with malignant tumor progression and better management of associated comorbidities. Dr. Harbaugh explains, “If patients have access to regular monitoring at an NF specialty center closer to their homes, it’s likely that tumors and associated complications will be detected earlier, possibly helping to avoid significant nerve and soft tissue damage and to preserve function.” Dr. Aregawi says, “Despite the fact that NF is a fairly common autosomal dominant disorder [1 in 3,000]¹, many adult patients are seen by specialists only when a problem arises, with routine follow-up mostly done in the primary care setting.” A major barrier to accessing specialty care is the limited care options closer to patients’ homes, with many required to travel long distances to see an NF specialist.

Adult NF patients often have very broad and complex medical needs. There are elevated risks for other diseases, such as hypertension, cataracts, breast and colon cancer, in addition to the well understood risks for malignant and nonmalignant brain and peripheral nerve tumors that can cause pain and loss of function. Most adult NF patients require treatment or consultations with a variety of specialists including a neurosurgeon, neuro-oncologist, genetic counselor, neuro-ophthalmologist, dermatologist, orthopaedic surgeons and plastic surgeons. A designated NF clinic serves as a home base and portal for access to this multidisciplinary care, making care coordination more seamless for both patients and providers.

Access to the NF clinic could also improve NF detection amongst family members and provide timely genetic counseling. Dr. Aregawi adds, “The course of NF is highly variable, even among close family members, so risks are difficult to estimate based on family history.” Dr. Harbaugh says, “With such complex needs, patients and physicians caring for those with NF need support and education. There are some very dedicated organizations that provide support and fund research, like the NF Tumor Foundation and the Children’s Tumor Foundation.”

The NF clinic specialists, Drs. Aregawi, Harbaugh and Rizk, focused primarily on adult NF patients in the past. Recently, they have started seeing pediatric patients and plan to incorporate additional pediatric specialty clinicians. They further plan to integrate clinical and bench-level NF research into the clinic program. Dr. Rizk notes, “Our basic science research is progressing rapidly and we are excited about prospects for clinical trials in the near future.”
